how to configure entity framework connection string when using sqlite

See more:

SQLite

EF6.0

i have created an outlook addin that uses a sqlite db and the entity framework, the application works 100% when running in debug with visual studio. I have then built a wix installer to install the addin which installs the addin without any problems, my issue is that when i try write to the sqlite db using the installed version i get the following error:

No connection string named 'TaskMonsterDBEntities' could be found in the application config file.

System.InvalidOperationException: No connection string named 'TaskMonsterDBEntities' could be found in the application config file.

i suspect my connection string in my app config is not correct, could anyone suggest what the problem is or a solution? my app.config looks like this:
